What Happens here?
After Quality Control, the material heads to the Eddy Current. This is a specially designed machine to sort aluminum.
How it works:
Since aluminum is not magnetic, it was not separated out with the cross-belt magnet. So this machine gives a positive charge to the aluminum and makes it jump up off the belt, over a separator bar, and into a holding bunker.
Where are the materials going next?
The aluminum falls into a holding bunker, and the trash and PET plastics head on to the Optical Sorter.
